USER GUIDE

7. Pre-installation guidelines • Place cables away from fluorescent lights, air conditioners, and machines that
are likely to generate electrical noise
• Place the Smart 216 on a flat, clean and dry surface or install in a rack
• Ensure that the maximum distance between each computer and the Smart 216,
does not exceed 30m/100ft.
7.1 Avoiding general rack mounting problems
Elevated operating ambient temperature
The operating ambient temperature of the rack environment may be greater than
the room ambient when installing into a closed or multi-unit rack assembly. So
install the equipment in an environment compatible with the maximum rated
ambient temperature.
Reduced airflow
Install the equipment in a rack in such a way that the amount of airflow required
for safe operation is not compromised. Leave a gap of at least 5cm/2” each side of
the Smart 216.
Mechanical loading
Mount the equipment in the rack in such a way that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit overloading
When connecting the equipment to the supply circuit, consider the effect that
overloading of circuits might have on over-current protection and supply wiring.
Reliable earthing of rack-mounted equipment should be maintained. Give attention
to supply connections other than direct connections to the branch circuit (e.g. use of
power strips).
